At least more than 95% people who buy health care products for middle-aged and elderly people do not sell them to themselves, but give them away to their parents, elders and so on.

And only 5% of the buyers are middle-aged and elderly. It is not the middle-aged and elderly people who really buy health care products for them, but the young people.

Therefore, leaflets should highlight elements such as filial piety and health, so that buyers can pay for their parents' health. Good luck. Slowly understand.
